SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 325,481, datedSeptember 1, 1885.

Application filed December 4, Iss4. (No mo lcLi To all whom it mayconcern:

Be it known that I, XVILLIAM J. BARRON, a citizen of the United States,residing at Huntsville, in the county of Madison and State of Alabama,have invented certain new and useful Improvements in Sash-Locks, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings.

The nature of this invention is a windowsash lock which consists in thecombination of an angular catch-bolt, a sliding spring-controlled rackand pinion, and means for rotating said pinion in order to retract saidcatch-bolt from aslot or recess in the stile of the sash when it isdesired to raise or lower the latter, into which recess it is projectedby the force of a suitable spring, as hereinafter particularlydescribed, and shown in the annexed drawings, of which- Figure lisaperspective view of the exterior of the lock detached from thewindow-frame. Fig. 2 is a like view of the same reversed, the plate 2',Figs. 1 and 4, being removed to reveal the interior mechanism. Fig. 3 isa side elevation of a windowframe, showing my device applied thereto.Fig. 4 is a horizontal section, as on line a b, Fig. 3.

Like letters of reference, where they occur in the several figures,indicate the same parts.

A marks the frame of the lock, which in the present instance isL-shaped, the wing of which that comes next the sash-frame beingprovided with a slot, 1), for the passage of the end (1 of thecatch-bolt E. O is a box-frame cast on the interior of the other wing ofsaid L-frarne,which box-frame is let into a mortise in the side of thewindowframe, as seen in Fig. 4.

R is a rack-bar having a part of one of its edges provided with teeth orcogs d. The catchbolt E is secured to or forms a part of said rack-bar,and is consequently movable therewith. Bar B rests against the sidesorflanges of the box-frame, and is also guided by means of a projectingplate, f, Fig. 2,which,with the side of the box-frame, forms a recess inwhich is contained a spiral spring, S.

P is a pinion secured to a stud, g, and provided with any suitablenumber of cogs, (2, adapted to engage with the cogs of the rackbar. Thisstud passes out through a hole in the lock-frame, and on its other endis secured a knob or button, H affording a means for rotating thepinion. The periphery of this button is preferably milled orindented,soas to furnish a hold for the hand in turning the same.

A plate or cover, 23, Figs. land 4, is fastened by means of a screwpassing into ahole, j,ina lug, k, on the side of thedivision-platef,thereby aiding to retain the rack-bar and spring inplace.

In applying the device to the window a mortise is out into the frontside of the frame 122-, and a recess, a, is made in the side of saidframe, as seen in Fig. 4, in order to allow free play of the part of thecatch-boltthat projects out through the slot 1) in the rack-frame. Thelock is then secured to the frame by means of a screw, .r. The edge ofthe sash-frame is provided with one or a series of recesses, Z, Fig. 4,at suitable intervals apart, for the reception of the projecting end qof the bolt E.

Although not essential, I prefer to secure a slotted plate, T, Fig. 4,over said recesses, in order to have greater durability than if the boltrested on the wood-work. I also prefer to provide the upper edge of theprojecting part of the bolt with a slot, to, Fig. 1, with which theupper edge of the plate engages, and thus avoid liability of the catchslipping or being pushed out from the recess, as it is then necessary toraise the sash a short distance before the bolt can be retracted.

It will be obvious that the spring S retains the projecting part, qwithin the recess; but when it is desired to elevate or lower the sashit is merely required to rotate the button H in the proper direction,thereby retracting the bolt.

When the lock is applied to the lower sash, it is secured to the 'windowframe near the top of the sash. \V hen applied to the upper sash, it issecured near the bottom thereof, as shown in Fig. 3.

I am aware of Letters Patent of Stoddard, No. 169,494, dated November 2,1875, and No. 134,542, dated January 7, 1883, of Heegler, and do notclaim anything shown or described in either of said patents.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a sash-lock, the combination of the slidingtoothed rack, the angular catch-bolt connected thereto, and thepiniomwith means for ICO rotating the same, substantially as and for theand button, all constructed and adapted to 0ppurposedescribed. eratesubstantially as and for the purpose set 2.
